B.name AS column_name,
C.value AS column_description
FROM sys.tables A
INNER JOIN sys.columns B ON B.object_id = A.object_id
LEFT JOIN sys.extended_properties C ON C.major_id = B.object_id AND C.minor_id = B.column_id
WHERE A.name = 'ND_Certificates_M'

2. 查询说明

select value,a.name FROM 
syscolumns a
inner join 
sysobjects d 
on 
a.id=d.id and d.xtype='U' and d.name<>'dtproperties'
left join 
sys.extended_properties g 
on 
a.id=G.major_id and a.colid=g.minor_id 
where d.name = 'CON_Review_M'
